摘要：

Selective laser melting (SLM) was used to fabricate Al-Cu-Mg alloy and Zirconium-modified Al-Cu-Mg alloy components. The hot-cracking phenomena during the SLM process was significantly reduced by the grain refining effect caused by the addition of Zr. Compared to the Al-Cu-Mg part, the Zr-modified Al-Cu-Mg part with the ultrafine grain exhibits increased yield strength (446 +/- 4.3 MPa) and ultimate tensile strength (451 +/- 3.6 MPa). These findings provide a basis for innovative alloy design for SW. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
